The answer is A.The calcium atom must bond with an atom of high electronegativity (like fluorine) because the higher electronegativity atom will bully the low electronegativity atom and take away its electrons.
These are the choices:
A. an atom with a high electronegativity, like fluorine
B. another atom with a low electronegativity, like lithium
C. another atom that would like to share electrons
D. no other atoms because it's too weak to bond with anything
It will have effect in the global climate change
Answer:
Plants. Some Bacteria. Algae. These 3 are the photosynthetic autotrophs..
Why the others don't fit:
Athropods are hetertrophs. Not all bacteria are autotrophs. Only some protists are autotrophs.
The plasma membrane and cell wall are two different structures. The cell wall is the outermost structure of plant cells, providing rigidity. The plasma membrane lies just inside the cell wall.
